The boran will add to the vinyl doublebond of styrene and build the Anti Markovnikov product. You have 2-Phenyl-ethylboran. With Peroxid you can oxidise it and get the alcohol. C6H5-CH=CH2 + BH3(CH3)2S => C6H5-CH2-CH2-BH2 + (CH3)2S C6H5-CH2-CH2-BH2 + 3 H2O2 + 3 OH- => C6H5-CH2-CH2-OH + BO3 3- + 5 H2O
